Metamorphic. By contrast, igneous rocks form from lava or magma, and sedimentary rock form from sediment. Those things are formed from previous rocks, but constitute intermediate stages: igneous and sedimentary rocks are formed indirectly from previous rocks.
Mineral composition of the magma, Rate of cooling of the magma, Temperature of the magma, Presence of volatiles and Amount of water present in the magma.

What type of rock is formed from magma that hardens underground?
a metamorphic rock
Sedimentary rocks are mainly formed by processes powered by the sun, such as weathering, erosion, and deposition. These rocks are made up of accumulated sediment that has been compacted and cemented together over time.
Dwayne "The Rock" Johnson. Atta baby.
sedimentary Mr. R This is incorrect. The answer is metamorphic.
A concretion is a rock formed from sedimentary processes; therefore, it is a sedimentary rock.
It varies with the type of rock being formed. Some igneous rock is formed in a matter of minutes; some sedimentary rock is formed in processes requiring many millions of years.
Sedimentary rocks, such as sandstone or limestone, are formed by processes like weathering, erosion, and deposition that are driven by the energy of the sun. These rocks are created through the accumulation and cementation of sediments produced by these processes.
All rock types can be formed from any other rock type.
Sedimentary rock is formed by the processes of erosion and deposition. Erosion breaks down rocks into sediment, which is then carried away by water, wind, or ice. When the sediment settles and gets compressed, it forms sedimentary rock.
The rock type formed as bits of other rocks are cemented together is called sedimentary rock. Sedimentary rocks are typically formed through the processes of erosion, deposition, and compaction of sediment particles. Examples of sedimentary rocks include sandstone, shale, and limestone.
The type of rock that likely formed first to initiate the rock cycle is igneous rock.
Igneous rock: Formed from the cooling and solidification of molten magma or lava. Sedimentary rock: Formed from the accumulation and cementation of sediments, such as sand, silt, and organic material. Metamorphic rock: Formed from the alteration of existing rock through heat, pressure, or chemical processes, without completely melting it.
Metamorphic rocks are formed when existing rocks are subjected to high heat, pressure, or chemical changes. This causes the minerals in the rock to rearrange and form new crystals, resulting in a new type of rock. The processes involved in the transformation of a rock into a metamorphic rock include heat and pressure from tectonic movements, as well as the presence of fluids that can alter the mineral composition of the rock.
